Your xorg.conf, Xorg log, and kernel log are a good place to look. Can
you reboot the machine and try to set the 2nd monitor to it's native
res? Once you do that you can grab your kernel log by doing the
following in a terminal:

dmesg >kernel.log

which will result in a file called kernel.log in your home dir.

After that attach kernel.log, /var/log/Xorg.0.log, and
/etc/X11/xorg.conf in your reply. You may not have /etc/X11/xorg.conf,
which is ok.
